• Carrier frequency: 13.56 MHz ± 7kHz

• ASK modulation 100%

and 10%

Two types of coding are supported by the transpondersfully compliant with ISO 15693:

1 out of 256: one byte is coded at a time

Example: coding 197 = <C5> = 11000101

time

ISO/IEC 15693Coding the information

1 out of 4: two bits are coded at a time

Example: coding 197 = <C5> = 11000101
